anchor worms in saltwater?

[ctreefer]

I bought some fish this past week from a local wholesaler. I tried to get a good look of the fish before bagging, but the space was cramped and I was in a hurry. As a result, one of my fish (squareback anthias) ended up coming home with something attached to it that looks like an anchorworm. From all I can find online it only seems they're in fresh water. I pulled it off this morning and this is what it looks like:

Any thoughts? It is about 1.5 inches from end to end. The fish is in quarantine with some other anthias. Should I also treat with copper or anything else? I did a fresh water dip before I put them from the bags to quarantine, but it was only about 5 minutes because one of the anthias looked like it wasn't going to make it. Now I'm guessing this is the one.

Well, 17 days have passed and I'm treating with hypo for an ich outbreak in same quarantine tank (29 gallon with 3 small anthias and one small potters angel) Today I notice a slight bulge behind the scales of my potters with a little white thing protruding. Possibly another one of these parasites. Can someone give me some input as to a good treatment to wipe these things out?

thanks

It does look like a parasitic copepod. Some species are called anchorworms. They usually are not a problem in aquarium fish. The females generally bury their heads into the tissues of the fish. Most are not life threatening unless its a large parasite on a small fish. The best treatment is to use is an organophosphate (such as dylox) in quarantine. Be aware of potential bacterial infetion in the wound caused by the parasite.

Thanks Terry,

Where can I get products that contain organophosphates like Dylox or one other I've found is Trichlorfon?

thanks
